Pros and cons
Garmin ECHOMAP UHD2 93sv with GT56UHD-TM Transducer
The 9-inch fish finder to buy if you want side imaging and lake charts on one sharp screen. On a smaller console, the 7-inch ECHOMAP UHD2 73sv gives the same sonar and charts.
Pros
- 1024 x 600 pixels on a 9-inch screen, against 800 x 480 on the STRIKER Vivid 9sv and Lowrance Elite FS 9
- Side and down imaging plus traditional CHIRP from the included GT56UHD-TM transducer
- Navionics+ U.S. Inland charts preloaded
- Built-in wireless shares sonar and waypoints with a second UHD2 unit, per Garmin
Cons
- Garmin does not publish a depth rating for the GT56UHD-TM; the 2,300 ft manual figure depends on the transducer
- Garmin's manual says no swivel base is available for the 9-inch models
- At 2.9 lb and over 10 inches wide, it is too large for most kayak dashboards
Garmin ECHOMAP UHD2 73sv with GT54UHD-TM Transducer
The fish finder to buy if you want side imaging and real lake charts in one 7-inch unit. Kayak anglers and anyone who only needs sonar should look at the STRIKER Vivid 7sv.
Pros
- Preloaded Garmin Navionics+ U.S. Inland charts, where the STRIKER units only map what you record
- CHIRP, ClearVü and SideVü sonar with the included GT54UHD-TM transducer
- Works with Garmin's Force trolling motor, controlled from the screen
- 500 W RMS sonar output
Cons
- 2.2 lb, heavier than the STRIKER Vivid 7cv's 1.7 lb, so it suits a console more than a kayak
- Garmin does not state the GT54UHD-TM's maximum traditional depth on the pages we read
- Inland charts only; coastal anglers need a different chart bundle
Choose the ECHOMAP UHD2 93sv if
- You split the screen between sonar and chart and want both readable.
- Your console has room for a unit about 10.4 inches wide.
Choose the ECHOMAP UHD2 73sv if
- You fish from a small boat with limited dash space.
- You want the same sonar and charts for less size and weight.
Both have built-in wireless, 5,000 waypoints and Navionics+ U.S. Inland charts. For more chartplotter picks, see our fish finders with maps list.
